I may then--I'm sorry. I'm making a mistake here.

接下来不好意思我这里写错了
This should be prime.

这里应该有一撇
By the way, when you guys do this,

顺便问一下你们刚才听课的时候
did anybody notice prime?

有人注意要加撇吗
If you noticed it, you got to stop.

如果注意到了你应该打断我
You cannot let me write anything that's incorrect.

你们不能容许我写下错误的内容
You got to follow it in some detail.

你们得注意一些细节
I know you couldn't do the details,

我知道你们不太注意细节
but you should at least know that it's i prime and j prime

但你们至少应该知道 i' 和 j'
that have been replaced by i and j.

已经被 i 和 j 取代了
But Ax prime and Ay prime will continue to be the coefficients.

但系数仍然是 Ax' 和 Ay'
So if I make a comparison,

所以如果我做一个比较
